My favorite snake deity is Coatlicue, whose epithets include “our mother”:
> Coatlicue is represented as a woman wearing a skirt of writhing snakes and a necklace made of human hearts, hands, and skulls. Her feet and hands are adorned with claws and her breasts are depicted as hanging flaccid from pregnancy. Her face is formed by two facing serpents, which represent blood spurting from her neck after she was decapitated.
Not mentioned: other representations of her with an intact, skeletal face.
What's fun about the Coatlicue statute, currently located in the National Museum of Anthropology in Mexico City, is that the earth deity is on the bottom. This statue is so large that one wouldn't be able to "tip" it over to look. Yet, there it is... a carving on the underside where no one can see it. Of course, the museum has a cast of the image adjacent where modern viewers can look at it. More about this kind of fun stuff is in Claudia Brittenham's book, Unseen Art: Making, Vision, and Power in Ancient Mesoamerica (disclaimer: she's my lovey wife).
